This invention appertains to new and useful `improvements in cooling apparatus and more particularly to a beer cooling keg. u

The principal object ofthe present invention is to provide cooling means for beer keg wherein the cooling means is constructed and arranged in such a manner as to obviate the necessity of bringing the beer into direct Contact with the said means.

Another important object oi the invention is to provide beer cooling means in the form of a i `specially constructed keg wherein a cooling rnediurn is circulated in a manner which will afford a uniform cooling action to the entire periphery ofthe beer column. l

These and various other objects and advantages of the invention will become apparentt'o the reader of the following specication.

In the drawing:

Figure 1 represents a top plan view.

Figure 2 isa side elevational view of the keg with portions in section.

Figure 8 is a fragmentary detailed section View on line 3 3 oi Figure l.

Referring to the drawing wherein like numerals designate like. parts, it can'be seen that the keg in construction consists "of the `outer shell 5 having the circumferentially extending ribs S. Numerals 'i 'and represent the upper and lower lwalls of the keg whichare constructed in the usualv manner and have their end portions clinched over the upper andlower edges of the shell 5 as at 9 and also overthe upper and lowerv and lower edgeportions of lthe walls lll and ll are brought together and `offset outwardly as shown clearly in Figure 2 to a point to meet the upper and lower edgesof the shell 5 where the upper and lower walls 'i and 8 are clinched over the same and further secured in any desired manner. Numeral l2. represents the usual bung and numeral i3 rep tube fitting.`

in further carrying out the present invention, a tube lll extends inwardly from the top wall 'l resents the usual eduction This tube i@ is `in `the `form of a coil extending downwardly in the space t and having its lower extremity it? open at the bottom of the space iii.

A. pair of couplings i'l and i8 are provided at l the top wall .l adjacent the edge thereof and preferably overlying the space iti and each of M. Hunsberger, Spring 1939, Serial No. `255,125

'l and also through the offset portion of the inner wall I ll. `Tubesy 22 of hard rubber or other similar material are disposable into the sockets I9 and each carries a transversely disposed pin 23' the end portions of which t into the lbayonet slotZb. The lower portions of the tubes 22 are provided with reduced depending tubular portions 2d over which can be slipped, in the case of the inlet tting il, the upper end of the tube Ill, with the upper edge portion of the tube lil flared outwardly against the internal shoulder of the corresponding socket i9. Gaskets 25 are provided in the' sockets to serve as packing means.

The upper ends of the tubes 22 are tapered as 15 at 26 and over these are slipped the rubber inlet i and strain-olf tubes 2l and 2i) respectively.

" It can now be seen that refrigerated liquid such as water is supplied to the .coil lll through the tube El and passes downwardly through the convolutions of the coil l and discharges from the open lower end it of the tube i4 into the bot-` torn` of the space i5. As the walls l@ and ll bear snugly against the convolutions of the coil lll, the coil will serve as a baffle and require the refrigerated liquid to pass upwardly following the coil l.` In other words, the upward passage of the refrigerated liquid must follow the convolutions of the coil and inl this way complete contact of the `outer side of the wall l is accomplished with the refrigerated liquid before it reaches the outlet tting i8 where it isy drawn off. This serves of course to cool the entire area ofthe wall l0 affording a uniform cooling action against the periphery of the beer column. l

While the foregoing specification sets forth the invention in speciic terms, it is to beunderstood that numerouschanges` in the shape, size and materials may be resorted to without departing from the spirit and scope ofy the invention as claimed hereinafter; l

Having described the invention what as new is: .l

'A beer keg comprising a container having spaced walls, a pre-cooled liquid inlet at one end of the keg, a coil inthe space between thewalls communicating at one end with the inlet and having its opposite end open, said container having an outlet at the inlet end of the container in communication with the space between the walls, said walls snugly fitting against the said coil to define the coil as a baille to form `a spiral passageway in the space between the Walls for the return of the pre-cooled liquid from the open end of the coil tothe outlet ofthe container. l
